Calculation
P = U · I
Power rises linearly with voltage and current; doubling either doubles P.
P = U·I

Result
Select a target and calculate.
Understand the inputs
- Supply or terminal voltage U — RMS voltage at the load terminals.
- Operating current I — RMS current in the operating state.
- Real power P — Product of U and I; AC power factor would need a separate input.
Example
230 V · 10 A = 2,300 W, or 2.3 kW.
Assumptions and limits
Single-phase DC or AC load with power factor 1.
